Thunderbolt 2 technology in ST4-TB is phenomenally fast. The two Thunderbolt 2 ports on ST4-TB features dual 20-Gbps channels for data transfer and that’s up to four times faster than USB 3. But beyond speed, Thunderbolt gives you unprecedented expansion capabilities. You can daisy-chain as many as six Thunderbolt devices to a single port. And since Thunderbolt is based on Display Port technology, Mini Display Port devices like Apple LED Cinema Display can plugs right in, too.

The ST4-TB built-in with two disk configuration modes: RAID 0 (Speed Mode), and JBOD (Four Independent Volumes) for you to choose according to your needs.

With two optional storage modes, user can choose between RAID 0 and independent mode. In RAID 0 mode, the enclosed four drives will be striped and combined into one large volume for storage to enhance the data transfer speed performance. Under the Independent mode, the enclosed drives are seen as four separate volumes instead of one single volume.

RAID 0 functionality increases storage speed and performance

The new ST4-TB is equipped with RAID 0 storage mode, which enables user to attain up to 724MB/s read speed with ST4-TB's Thunderbolt transmission interface. Whether it is used for searching and editing photo galleries, or video editing and synthesis, it promises to deliver a smooth and easy operation.

Stylish and rugged

The ST4-TB has a sleek exterior design that’ll never go out of style when placed next to your Mac. It’s also built tough with three millimeter thickness aluminum to shield the enclosed drives durably and to dissipate the heat created by the drives faster for the drives to work comfortably.

The ultimate all-in-one demands the most advanced I/O technology. Each tiny Thunderbolt port lets you expand the capabilities of your Mac for connecting high performance peripherals, transfer data at high speed, or even daisy-chain multiple devices. And the new iMac with Retina 5K display has Thunderbolt 2 built-in, delivering twice the bandwidth — up to 20 Gbps — for the fastest data transfers.

To help you complete your photography projects

With two ultrafast Thunderbolt 2 ports, you can build a photo studio around MacBook Pro and T4-TB. Or take them with you and import thousands of RAW images on location — up to six times faster than on a standard MacBook Pro. Once your photos are on your computer, editing in Aperture is faster and more responsive than before.
ST4-TB's RAID 0 mode lets you quickly browse large image libraries from external storage. So you have instant access to any photo in your library.

Environmentally friendly.

ST4-TB is made from highly recyclable aluminum and it is also free of many harmful toxins which commonly present in the desktop computer manufacturing process.

Advanced power management.

ST4-TB uses energy-efficient hardware components that work hand in hand with the Mac system to conserve power. It spins down hard drives and activates sleep mode after a period of inactivity.
